Electrical Systems
ENTRY LIGHT:
Key for turning ENTRY LIGHT on and off.
The entry light also goes on automatically for
15 minutes in the following cases:
- when the ignition key is removed
- when the rear door is opened / closed
- when the cab door is opened
The key on the control panel has priority over
the 3 situations described above. The entry
light works also with the control panel off
and the engine / alternator running. The entry
light goes off automatically if the voltage of
the leisure battery drops below 10V for more
than 3 min.
INTERIOR LIGHTS:
Key for turning INTERIOR LIGHTS on and
off. The interior lights do not go on when the
control panel is off or if the engine is running.
ROOF LIGHTS:
Key for turning ROOF LIGHTS on and off.
This key does not work if the interior lights
are off.
CAB BATTERY:
Press this key to access the possibility to
power services with the CAB battery (red led
on). Services are normally powered by the
leisure battery (red led off). To protect the
cab battery from discharging, the system
switches back to the leisure battery in the
following conditions:
- if the cab battery voltage drops
below 11.75V
- when the vehicle ignition is ON
- when the control panel is off
When the the engine is running the leisure
battery is connected to the cab battery, in
this way the alternator can charge both
batteries.
FRESH WATER TANK HEATER:
This function is enabled when the level of
fresh water in the tank is greater or the same
as
1 ⁄
4
(if there is an analogue probe, greater or
the same as 20%). Tank heating does not
work when the control panel is off. If the
engine is running it works also with the
control panel off.
FRIDGE:
When the engine / alternator is running the
fridge relay is energised, ensuring a supply of
12V energy to the fridge.
HOB - TV:
These functions are constantly supplied
with 12V, except when the engine is running
and the control panel is turned off.
